My-present invention has for its object to provide an extremely simpleand highly efficient self-dumping barge, and to thislend it consists ofthe novel devices and combinations of devices hereinafter described anddefined in the claims. p

The improved barge `is especially `welladapted for handling materials'for wet storage such as coal and iron ore.l "Inthis use of the bargethe materials will behauled from mines or docks and dumped into deepchannels or ponds where they ma bereadily removed by, for instance, clams elllbuckets mounted on bridge cranes or otherwise, when needed. Saidbarge is also welladaptedfor use in `connection with a dredging outfit'to carry excavated materials to a distant point and dump the same intoafbody `ofwwater for `the purposeof making `a fill `or tojsimplywastethe material.` ylrlie barge may? alsobe used for. various otherdilerent purposes such as hauling refuse from cities and dumping thesame indeep water.` d A Inthe accompanyingdrawings, which illustrate theinvention, likecharacters indicate like partis throughout the severalviews.

many uses for which the improved barge may be used, to wit:thetransportation of coal `from amine or dockand deposit of the -w .lReferring now in detail same in a channel, pond or the like, there isillustrated in the drawings a body of `water 8 whichm'ay be alake,river, streamer pond and that is excavatedto such a depth as toali'ord a `relatively large basin 9 Aand a relatively-small basin 10. Onthe land side of the basinl9 is a `coal yard or dock 11.` y d Forremoving the coal `from the `basins 9 and `1() and depositing the samein a pileon the dock 1l or'in4 cars 12, there is provided a clam shellbucket `13 carried'b `a carriage 14 mounted to travel on-the bri gecranel. Thisbridge crane 15 ismounted to run on three parallel tracks16, the outer of which is onpiers 17 and the intermediate track 16 is ona wall or pierslpatthe outer endof the dock or yardgllr `A house 19 for`the operator of the clam@` shell `bucket 13 and :crane 15 is mountedoni the bridge crane 15.

to the improved barge, `the numeral 21 indicates the'` hullthereofconstructedof sheet steel, the plates Y of which. are preferablyconnected by ,welding.. Extending longitudinally `through the `hull 21:at the transverse `center thereof isa vertical partition 22 which`divides said hull into twov equal air-tight compartments 23 and 24.Thesecompartments 23 and 24. give Y the `barge therequiredbuoyancysothat said Within thecompartment 24 `at the outer sideofthe `hull 21, and at the longitudinal Center thereof'isfa `scuttlevalve 25 which nominally closes a portin the `bottom of the :hull 21.Theupright stem 26 of the scuttle valve 25 Yis mounted in` a fbearing 27` on `the `adjacent sidey of the hu1121, and keyed to fthe upper endofsaid slem'is a bevel` gear f 28. I A bevelgear129 meshing with thebevel .gear `28 is keyed te` a` horizontal shaft` 30 `which extendslongitudinally` through the `compartments24and`iis connected by a air 4y y lof bevelgears 31 tothe lower `endzo `an` For fthe purpose `ofshowing -oneof the provided with `a hand wheel-34. By :the

valve is an air conduit 35, `the outer end portion of which is bentupright and projected through the deck 33 and thereabove. i

A screw cap 36 is applied to theupper end of the air conduit 35 andnormally closes the same. This cap 36 is secured to the hull 21 by achain37 to prevent said cap from being droppled overboard. The lnner endportion of t e air conduit 35 extends into the compartment 24 throughthe artition 22 and is bent vertically downwar and terminatesconsiderably above the bottom of the 11111121. The top of the deck 33 isflat and secured thereto in rectangular arrangement are side and endboards 38. .One of the sido boards 38, to wit: the one on the same sideof the barge as the scuttle valve 25, has its lower longitudinal edgehinged at 39 to the deck 33 for outward swinging movement onto saiddeck. This hinged side board 38 is held upright by a plurality ofoblique stakes 40. The deck 33 outward of the hinged side portion, iscountersunk at 41 to receive said side board and hold the same with itsupper face flush with the top of the deck 33.

Secured to the deck at each end of the barge isa pair of cleats 42 foruse in tying the barge to another barge or to a dock.

To dumpy the load of coal w from the barge, said barge is towed to thelace where the coal is to vbe Vstored in the bo y of water l8. Theoperator first removes the stakes 40 to let down the hinged side board24. Next, he removes the cap 36 from lthe air conduit 35 and thenoperates the hand wheel l34 to open the scuttle valve 25. After theseoperations, the operator steps onto an adjacent 'barge Aor. tow-boat soas to be out of the wai during the dumping action of the barge.

s the water enters the compartment 24 through the `scuttle valve 25, theair in said compartment escapes through the air conduit 35Vto theatmosphere. Under the weight of l the water in' the compartment 24, therespective side of the barge is overbalanced and settles into the Vwaterand thus starts the sliding of the coal a: from thev deck 33. Thisshifting ofthe load of coal on the Vdeck 33 greatly accelerates thedumping or tilting action of the barge. As the inclination of the bargeincreases, the water in the compartment 24is shifted outward and theadded weight thereof further assists in tilting the barge until theinclination thereof is n such that the coal will Vslide therefrom, as

r`shown in Figs. 1 and 6. After the coal w has been ldischarged from thebarge, the

bouyancy of said barge will cause the same to shoot to the surface ofthe water and rescuttle valve 25. It will thus be seen that only enoughwater is taken into the compartment 24 to produce-the necessary dumpingr action.

he empty barge is then towed to a dock 42, or in some instances atow-boat, andsecured b a cable 43. The upper 'end of the air con uit 35is then connected by a hose, 44 to the hydrant 45 of an air com ressor,not shown. l,Air is then forced into t ie compart-A ment 24 to expel thewater therefrom through the scuttle valve v25. After the water has beenexpelled from the compart# ment 24 the scuttle valve 25 is closed andthe cap 36Y applied to the air conduit 35. i-

While the improved barge is shown constructed of steel, it may be madefrom wood or other suitable material. I tvisfalso understood that thebarge may have a multiplicity of air compartments. In the drawings, ahydrant for an air compressor islshown onV a dock, but in allprobability thefmost convenient place for the same togetherfwith an aircompressor or compression tank will been a tow-boat handling the barges.i i

What I claim is: n l r 1. A self-dumping barge 'having a flat deck Ywithside boards, one of which is hinged to kthe deck at its lowerlongitudinalzedge ,for

outward swinging movement ontoY the .deck said deck outward of itshinged sideboar being countersunk to receive saidv side board with its uper face substantially flush with thetopo thedeck. s

2. A self-dumping bargevhavinga closed hull, a scuttle valve for thehull and a normally closed air conduit leading from the hull, said bargehaving means for confining hull and automatically stop'further intake ofwater `through the scuttle valve, means for dlscharging the water from`the hull `through the scuttle Vvalira-and means for closing the scuttlevalve..-

3. self-dumping barge havi g aclosed hull, a scuttle valve for the hull,a normally closed air conduit leading from the hull, said arranged to besealed b the water inAv barge having means for confinin water taken intoits hull through the scutt e valve to overbalance and tilt said barge,said con.

duit, when open, permitting the escape of air from the hull during theintake of water through the scuttle valve, said conduit being arranvedto be sealed by the water in the hull ater a predetermined intakethereof to prevent further escape of air from the hull and automaticallystop further intake of water through the scuttle valve, and means forforcing air into the hull through the air conduit to expel the waterfrom the hull throu h the scuttle valve.

4. A sel -dumping barge having two closed air compartments, a scuttleyvalve for one of the air compartments, a normally closed air conduitleading from the compartment having the scuttle valve, said conduit,when open, permitting the escape off air through said connectedcompartment during the intake of Water through the scuttle valve, and

meansfor forcing air into said compartment to expel the water therefromthrough the y scuttle valve.

5. .A self-dumping barge havin two closed air compartments, a scuttle vave for one of the air compartments, a normally closed air conduitleading from the compartment having the scuttle valve, said conduit,when open, permitting the escape of air from said connected compartmentduring the intake of water through the scuttle valve, said conduit beingarranged to be sealed by water in said compartment after a predeterminedintake thereof to prevent further escape of air from said compartmentand automatically stop further intake of water through the scuttlevalve, and means for forcing air into said compartment through saidconduit to expel the water from said compartment through 'the scuttlevalve.
